Coated tablets

Tablet cores may be coated with layers of sucrose, a thin film of resin or a soluble wax. This may be to make the medicine more palatable, to protect the active ingredient from exposure to air, light or moisture, to delay the absorption until it reaches the small intestine or to extend the duration of action. Products may also be coated to give them a more attractive appearance. Sugar-coated tablets vary more in dimensions (both size and weight) than uncoated or film-coated products. Markings printed on sugar coated tablets may often rub off quite easily. The sugar coating also tends to ‘round off’ the edges of the core, so that sharp edges become rounded. Sugar-coated tablets may closely resemble confectionery in both appearance and taste, at least initially, and may be consumed inadvertently by children who believe them to be sweets (candy).
